On October 10, PetroChina Guangxi Petrochemical’s 270,000 tons/year propylene oxide/styrene unit project started construction. The 27/600,000 tons/year propylene oxide/styrene unit is an important device in the PetroChina Guangxi Petrochemical Refining and Chemical Integrated Transformation and Upgrading Project. The total investment of the project exceeds 3 billion yuan and covers an area of about 150,000 square meters. It mainly includes ethylbenzene. , peroxide, epoxidation, PO
Refining, phenylethyl alcohol dehydration, styrene refining and other process units and public works and auxiliary facilities, the main products are propylene oxide and styrene. The device is contracted by China Huanqiu Engineering Co., Ltd. and constructed by China Petroleum and Natural Gas Construction Co., Ltd. No.6.
The project is scheduled to be completed on June 30, 2025.
According to Huizheng Information’s understanding, the transformation and upgrading of PetroChina’s Guangxi Petrochemical Refining and Chemical Integration is a major project in the national petrochemical industry planning and layout. It is also a strategic project for China Petroleum Corporation to promote “reducing oil and increasing chemical” to adjust the structure. It has been included in the national “Petrochemical Industry Plan” “Industrial Planning and Layout Plan” planning projects, the autonomous region’s top ten industrial projects in 2022, and the autonomous region’s “Double Hundred and Double New” major industrial projects. On July 27, 2022, Qinzhou City and PetroChina Guangxi Petrochemical Company signed an investment agreement for the PetroChina Guangxi Petrochemical Refining and Chemical Integrated Transformation and Upgrading Project.
The project is located in the Petrochemical Industrial Park of Qinzhou Port Area of Guangxi Pilot Free Trade Zone, with a total investment of approximately 30.5 billion yuan. It is planned to be fully launched on July 28, 2022, and will be completed and put into operation in 2025. After it is put into operation, the annual output value is expected to be approximately 30 billion yuan, and the tax revenue will be approximately 30 billion yuan. billion. The project relies on the existing crude oil processing capacity of PetroChina Guangxi Petrochemical’s 10-million-ton refining project and uses light naphtha and other products produced by the refinery as raw materials to build a new million-ton ethylene cracking and downstream deep processing unit. After it is put into operation, it will add ethylene, The production capacity of basic chemical raw materials such as propylene and butadiene is about 2.76 million tons, and the extension of the development of high-value-added products such as high-end polyolefins, EVA (ethylene-vinyl acetate copolymer), and solution polymerized rubber will help alleviate the current overcapacity in refining but the basic The contradiction between supply and demand due to the shortage of chemical raw materials will fill the gap in the regional high-end chemical new materials industry, meet the market demand in areas along the “One Belt, One Road” and the Western Land-Sea Corridor, build a new development pattern for high-quality industrial development and services in Guangxi, and accelerate the establishment of a trillion-level industry. High-end new materials industry clusters are of great significance.
PetroChina Guangxi Petrochemical Refining and Chemical Integrated Transformation and Upgrading Project mainly includes:
The Refining Area block relies on the existing 30 sets of main production units to build a new 2 million tons/year diesel adsorption dearomatization unit and a 400,000 tons/year carbon recovery unit (including
100,000 tons/year catalytic dry gas carbon dioxide recovery unit and 400,000 tons/year carbon dioxide recovery unit, built in the chemical industry zone), out of service 2
Set of main production equipment. After the completion of the project, the overall processing flow of the refining block will remain unchanged, and some of the refining product plans will remain consistent with the current situation. However, the annual production of gasoline and diesel will be reduced, and a large amount of high-quality raw materials will be provided for downstream ethylene units.
14 new sets of main chemical equipment will be built in the Chemical Industry Zone block, including
1.2 million tons/year ethylene unit, 550,000 tons/year pyrolysis gasoline hydrogenation unit/styrene extraction combined unit, 180,000 tons/year butadiene extraction unit, 10/60,000 tons/year MTBE/butene- 1
Equipment, 350,000 tons/year aromatic hydrocarbon extraction unit, 400,000 tons/year full density polyethylene unit (FDPE), 300,000 tons/year high density polyethylene unit (HDPE), 300,000 tons/year tubular ethylene-acetic acid Ethylene ester plant (EVA), 100,000 tons/year kettle ethylene-vinyl acetate plant (H-EVA), 400,000 tons/year polypropylene plant (PP), 50,000 tons/year hexene-1 plant, 27 /600,000 tons/year propylene oxide/styrene plant (PO/SM), 300,000 tons/year polystyrene plant (PS)
and
The 120,000/80,000 tons/year solution-polymerized styrene-butadiene rubber integrated unit (SSBR/SBS) mainly processes different types of cracked raw materials from the oil refining block and produces high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), Ethylene vinyl acetate (EVA), polypropylene (PP), butadiene, methyl tert-butyl ether (MTBE), butene-1, hexene-1, solution polymerized styrene-butadiene rubber (SSBR), styrene -Butadiene-styrene (SBS), propylene oxide (PO), styrene (SM), polystyrene (PS) and other major chemical products. At the same time, the environmental protection measures, storage and transportation systems, and public works of the entire plant will be newly built, renovated, expanded, or reused according to the process flow.
Dock storage area Build four new 5000m3 styrene storage tanks in the reserved area; in addition, the existing 13# berth benzene loading facility at the dock will be changed into a benzene unloading facility.
Two gasoline loading and unloading arms and one diesel loading and unloading arm in berth 11# were changed to benzene, toluene, and xylene loading and unloading arms respectively, and
New styrene loading facilities have been added to berth 9#. At the same time, the environmental protection measures, storage and transportation systems, and public works in the terminal storage area and terminal will be newly built, renovated, expanded, or reused according to the process flow.
